During the last few International Development Association (IDA) replenishment negotiations, several large donors have pressed for reforms to further increase the share of IDA resources provided to the neediest and most vulnerable countries. This paper explores just how well IDA’s existing performance-based allocation (PBA) system actually addresses these issues. To achieve this, the author examines how IDA allocations are distributed at each successive stage of the PBA methodology based upon a number of need and vulnerability measures.
